输入/输出模块是可编程控制器PLC与工业生产设备或工业生产过程连接的借口。现场的输入信号,如按钮开关,行程开关、限位开关以及传感输出的开关量或模拟量(压力、流量、温度、电压、电流)等,都要通过输入模块送到PLC。由于这些信号电平各式各样,而可编程控制器CPU所处理的信息只能是标准电平,所以输入模块还需将这些信号转换成PLC能够接受和处理的数字信号。输入模块的作用是接收中央处理器处理过的数字信号,并把它转换成现场执行部件所能接收的控制信号,以驱动如电磁阀、灯光显示、电机等执行机构。可编程控制器有多种输入/输出模块其类型有数字量输入/输出模块和模拟量输入/输出模块。这些模块分直流和交流、电压和电流类型,每种类型又有不同的参数等级,主要有数字量输入/输出模块和模拟量输入输出/模块,部件上都设有接线端子排,为了滤除信号的噪声和便于PLC内部对信号的处理,这些模块上都带有滤波、电平转换、信号锁存电路。数字量输入模块带有广电耦合电路,其目的是把PLC与外部电路隔离起来,以提高PLC的抗干扰能力。数字两输出有继电器输出、晶体管输出和可控硅输出三种方式。模拟量输入/输出模块主要用来实现模拟量与数字量之间的转换,即A/D或D/A转换。由于工业控制系统中有传感器或执行机构有一些信号是连续变化的模拟量,因此这些模拟量必须通过模拟量输入/输出模块与PLC的中央处理器连接。模拟量输入模块A/D转换后的二进制数字量,经光电耦合器和输出锁存器宇PLC的1/0总线挂接。现在标准量程的模拟电压主要是0—5伏和0—10伏两种。另外还有:0—somV、0—IV、—5—+SV、—10—+10V,0—10mA等。模拟量输入模块接收标准量程的模拟电压或电流猴,把它转换成8未、10未或12位的二进制数字信号,送给中央处理器进行处理。模拟量输出模块将中央处理器的二进制数字信号转换成标准量程的电压或电流输出信号,提供给执行机构。
